Alpinia galangal, commonly known as galangal, has a long history of use in traditional medicine, especially in Southeast Asia. It has been used in ethnomedicine to manage various ailments, including respiratory infections such as influenza. The traditional use is based on the belief that galangal possesses warming, expectorant, and anti-inflammatory properties, which might help relieve symptoms like cough, sore throat, and congestion associated with influenza. In Thai and Chinese herbal practices, decoctions or infusions of galangal rhizome are commonly administered for colds and flu-like illnesses.

From a scientific perspective, there are limited studies examining Alpinia galangal specifically for influenza. Some in vitro research indicates that galangal extracts may exhibit antiviral activity against certain viruses and possesses immunomodulatory effects. However, direct evidence supporting its efficacy against the influenza virus in humans is lacking. The existing scientific data are preliminary and insufficient for a strong recommendation. Most of the support for galangal’s use in influenza comes from traditional knowledge rather than robust clinical research.

In summary, while Alpinia galangal is traditionally used to manage symptoms of influenza and there is some weak scientific rationale, the overall evidence is limited. Its use for influenza should be considered complementary and not a substitute for evidence-based treatments such as antiviral medications and vaccination.
